Macroblock Introduces A High Efficiency, Constant Current And Step-Down DC/DC Converter- MBI6651

Macroblock introduces a new step-down DC/DC converter, MBI6651, to drive 1A output current with efficiency up to 93%. With merely 0.45ohm of switch ON resistance, MBI6651 reduces the power consumption on IC at rated voltage. Additionally, the internal start-up scheme eliminates the inrush current and limits it within 1.15 times of preset current. Besides, MBI6651 features constant current and provides uniform brightness with excellent output current accuracy up to ±5%(Max.).
